Image quality scores and quantitative analysis will be compared using both standard and the novel reconstruction algorithms. These results will also be compared to the acquired FC levels. Because each patient examination will receive multiple reconstructions, a mixed-model analysis will be conducted to account for repeated observations within patients. Repeated measures analysis of variance will be conducted separately for each outcome (signal, noise, SNR, proportion of interpretable segments, and image quality) against the type of reconstruction used. A 0.05 significance level will be used for all repeated measures and analysis.
